Kaspersky Security Center is a distributed application. Rolling back the file system to a previous state on a device with Network Agent installed will lead to data desynchronization and improper functioning of Kaspersky Security Center.
The file system (or a part of it) can be rolled back in the following cases:
Scenarios under which third-party software on devices with Network Agent installed affects the %ALLUSERSPROFILE%\Application Data\KasperskyLab\adminkit\ folder are only critical scenarios for Kaspersky Security Center. Therefore, you must always exclude this folder from the recovery procedure, if possible.
Because the workplace rules of some organizations provide for rollbacks of the file system on devices, support for the file system rollback on devices with Network Agent installed has been added to Kaspersky Security Center, starting with version 10 Maintenance Release 1 (Administration Server and Network Agents must be of version 10 Maintenance Release 1 or later). When detected, those devices are automatically reconnected to the Administration Server with full data cleansing and full synchronization.
By default, support of file system rollback detection is enabled in Kaspersky Security Center 14.2.
As much as possible, avoid rolling back the %ALLUSERSPROFILE%\Application Data\KasperskyLab\adminkit\ folder on devices with Network Agent installed, because full resynchronization of data requires a large amount of resources.
A rollback of the system state is absolutely not allowed on a device with Administration Server installed. Nor is a rollback of the database used by Administration Server.
You can restore a state of Administration Server from a backup copy only with the standard klbackup utility.
